PROBLEM TO BE SOLVED: To provide a QCM analyzer for stably detecting a change only in the adsorption of an object. SOLUTION: In the QCM analyzer for utilizing an antigen-antibody reaction for selectively adsorbing an object to adsorb the object on the surface of the electrode provided to a vibrator, a liquid 20 mixed with the object is brought into contact with a support substrate 1 on which the vibrator having a reaction film is applied and, after a certain reaction time, the support substrate 1 is separated from the liquid 20 by a separation means due to a lift part to detect a stable and accurate weight change without being affected by an unstable liquid.
